I was aware that JPGraph was indeed used for graphs for other weather programs, however unless the files are in exactly the same format my graph package will not work since I use the WD format only. However having said that if people can send me the equivalent files for other programs, together with the details of the file structure, I am quite happy to convert my graphs where I can if the data is available in the files. I cannot promise how quickly I would be able to do this but am quite willing to have a go as time permits.
